Résumé: The Filter Bank Multicarrier with Offset Quadra-
ture Amplitude Modulation (FBMC-OQAM) is emerging as one
of the alternatives to Orthogonal Frequency Division Multi-
plexing (OFDM) for next generation broadband wireless access
systems. In this paper, we focus on the nonlinear distortion effects
in a FBMC-OQAM system when the signal is passed through
a nonlinear High Power Ampliﬁer (HPA) which is modeled as
Saleh’s one exhibiting amplitude and phase distortions. First, we
develop an analysis showing that the FBMC-OQAM signals are
more sensitive to the phase distortion than OFDM signals. Then,
we address the problem of the compensation of these distortions
in FBMC-OQAM systems using digital predistortion (DPD) at
the transmitter. Therefore, two DPD schemes are considered in
this investigation and their performance are compared in OFDM
and FBMC-OQAM systems.
